Special Issue Information

Dear Colleagues,

Books, documents, packaging and contemporary artwork represent valuable products in graphic technology and an indispensable part of modern lifestyle. For a high-quality product, the careful selection of materials is essential. This applies to various printing materials, from plain office paper to special and recycled papers and synthetic polymer materials, as well as to advanced printing inks, which must meet high expectations regarding the appearance and usability and also ecological requirements.

Color science has a special place in this story. An average observer with normal color vision can perceive millions of color shades, and it is the optical properties of a product that are often the most obvious and most quickly recognized. The optical properties of materials, including color, eventually change and deteriorate under the influence of external factors, especially light. By studying the process of photodegradation and understanding the properties of materials, we can predict, control and even prevent unwanted effects.  

This Special Issue will focus on the latest research in the field of graphic materials, printing technologies, durability of prints and the role of color science in this process. The researchers are invited to present their work in the form of scientific or review articles.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Comparative Analysis of Anthraquinone Reactive Dyes with Direct Dyes for Papermaking Applicability

Aiming to compare the applicability and the successfulness of reactive dye printing papers’ coloration, two laboratory-synthesized anthraquinone reactive dyes are studied in comparison with two commercially available anionic and cationic direct dyes. Reactive dye 1 is monochlorotriazine and reactive dye 2 is bifunctional (contains two reactive groups—one is a monochlorotriazine atom and one an unsaturated allylic group). The synthesized reactive dyes are investigated through a paper slurry, white waters and paper sample properties comparative analysis. The drainage ability, flocculation volume and sedimentation index of paper slurries are determined. The turbidity, conductivity, pH and dye concentration in the white waters are also examined to ensure dye fixation. Through SEM, the paper structure is evaluated. The strength properties, colorimetric characteristics and stability at accelerated light aging of all 15 paper samples are investigated. The dewatering ability is enhanced, the white waters are clarified, the conductivity and pH level are stable and the dye concentration is on the same levels as for the direct dyes. The paper structure is uniform, the strength is slightly enhanced and color differences are indistinguishable compared to those of the direct dyes, when the ratio of the fixing agent to dye is appropriately optimized.
